Vessels MCP exposes catalog tools (search, track, nearby, green, ports, position) on https://mcp.vessels-api.com. Auth is the same X-API-Key family as REST.
Starter is $19.99/mo (2,500 calls) with a 7-day trial. Envelope is {status,success,message,data}. There is no geofence endpoint — use nearby with lat/lon/radius.
REST sibling: official track (2026-02-09)
curl -H "X-API-Key: YOUR_API_KEY" \
"https://vessels-api.com/api/V1/vessel/track?mmsi=258785000"
Homepage / docs fixture: MMSI 258785000, vessel ZJ ATLANTIC, dated 2026-02-09. Do not invent extra positions. Live-position is Professional+ and a separate quota.
